rv

rv is a 64-bit RISC-V emulator written in Go.

Limitation

32-bit, 128-bit aren't supported.
- Only RV39 is supported as memory translation.
Multi-core emulation isn't supported.
release/acquire bits are not handled in AMO instructions.
- rv currently emulates only one hart, so this is not really a problem.
fence instructions do nothing.
- rv currently does not apply any optimizations and no out-of-order execution occurs, so it should be fine.

go install github.com/hidetatz/rv@latest

Pass an ELF program to run to rv.

rv -p ./hello

Debug log will be enabled if -d option is passed (note that this dumps all the executed instructions and some other information).

rv uses riscv-tests as its E2E test. You can run that by following command:

go test -v ./...

For the full list of the implemented instructions, see instruction.go.
